It looks like we're getting Valvatorez's flashback episode this next March 13, along with a Makai Map, a Kingdom Tank, Pram, and Nisa (from Hyperdimension Neptunia). NISA seems more excited about Fuka & Desco's Show episode set (for release next May) given there's a trailer for it, as seen here: http://disgaea.us/d4/movie.html
